VAT FOR PAPER-MAKING MACHINES.

SPECIFICATION forming part of Letters Patent No. 323,079, dated July 28,1885.

Application filed May 19, 1885. (No model.)

To all whom it may concern.-

Be it known that I, JOHN F. SEIBERLING, of Akron, county of Sum mit, and State of Ohio, have invented a new and useful Improvement in Vats for Paper-Making Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this specification.

My invention relates, first, to a novel construction of vat, in which the rear makingcylinder is elevated above the plane of the other cylinder or cylinders in a manner similar to that described in Letters Patent granted to M. Seiberling, February 11, 1879, N 0. 212,155, whereby a single pump is made to force the exhaust-water from all the cylinders back into the vat or mixingchamber, and whereby also a single pipe is made to connect both the upper and lower vats with said pump; second, to a novel construction of the covers to the receptacles for knots and other heavy substances, and to the means for operating the same, whereby less agitation of the contents of the receptacles is produced than with the devices heretofore used, and, third, to the means employed for cleaning the felts and cylinders, whereby I am enabled to clean them without stopping the machine, as hereinafter described.

In the accompanying drawings, Figure 1 is a side elevation of my improved vat, with the side walls partly broken away to show the arrangement of parts. Fig. 2 is a plan View of the same. Fig. 3 is an end elevation, with the lower portion broken away. Fig. 4 shows the cleaner in side elevation; and Figs. 5 and 6 show the cleaner in different forms, the one in section, and the other in end elevation.

A and A represent the two parts of the outer tank or vat, made, by preference, in the form of rectangular water-tight compartments, and arranged one, A, on a higher plane and in such relation as to adapt it to feed the other by its overflow, as will be described.

Within the lower larger compartment, A, is arranged one or more inner tanks or vats, B, similar in form to the other compartment, A, except that its bottom is raised above, and, by preference, set at an inclination to the bottom of tank A, and terminates at one side in a curved side wall, 0, conforming in curvature to the adjacent side of the cylinder D, arranged in said vat or tank, and withthe upper edge of said wall terminating below the plane of the upper edge of tank A to adapt it to fill from overflow into it from the latter.

The tank A may be enlarged to contain additional tanks or inner vats and cylinders, as shown at B D and a similar inner vat may be placed in the tank or compartment A, in connection with'the upper cylinder, D, if desired, this arrangement serving to give the knots and heavy foreign substances opportunity to settle in the outer tank, and thereby to present the pulp in much better condition to the making-cylinders than where the single or outer tank or vat only is employed.

The upper tank or vat, A, has two or more compartments or chambers, formed by partial partitions a a for facilitating the thorough mixing of the pulp before it reaches the making-cylinders, and is connected with the lower vat, A, by a pipe, at, (or c and a, one on each side,'as shown in Fig. 2,) provided in the vat A, with a gate, a to regulate the overflow from vat A through the pipe a into the vat A. The exhaust-water from the pulp passes into the cylinders, and thence through suitable openings at the ends thereof into a pipebox or pipe, I), communicating with the several cylinders and with a box or close compartment, E, which at one end has a pump, E, of any suitable construction, connected with it at c, from which a water-pipe, 6, leads to the mixing trough or box F, into which such exhaust-water is forced for use again, in a manner well understood. A pipe or box may be used on each side of the tank or vat, as indicated at b and b, Fig. 2, for facilitating the drawing off of the exhaust-water, both communicating through the compartment E and pipe 6 with the one pump at E.

The stuff-box is indicated at F, arranged above the mixing-box F, and connected with the latter by a stutfpipe, f, and the mixingboX is in turn arranged above the compartment A of the vat, for facilitating the discharge of its contents into said compartment, in any suitable manner.

The arrangement of the felts or endless apronsG and H is similar to that described in Patent No. 212,155, referred to, except that for facility in cleaning I prefer to arrange a portion of the latter over the mixing trough or box to travel in a vertical path,as indicated at H, so that the material taken therefrom, together with the water and acid used in cleaning, will fall into said box and be mixed with the contents thereof.

Above the mixing-box F is arranged the upper felt-washer or pipe or sprinkler, Z and felt-cleaner n, so that the water from the pipe will drop into the mixing-box.

The receptacles for knots or other heavy substances, such as would be liable to injure the paper or straw board, are arranged in the vat in the same manner as described in my patent of February 17, 1885, No. 312,390; but the covers I of such as are in the inner vats, or such as work over curved sides, are jointed to adapt them to follow such'sides, as shown that is, they are composed of two or more parts'or slats. connected on their upper faces by hinges i in such manner as to permit them to partly fold upward in following the curved wall of the vat on which they rest. 7 They are provided with rods attached at one end to the edge of the cover or its lower side, one at each end, and with their opposite ends projecting through perforations in the side wall of the receptacle, and provided with toothed racks j, which engage with pinions on a shaft, which at one end projects through the side wall of the vat, and is provided with a crank or other suitable means for operating it. WVhere the wall of the vat is not curved the joints in the cover will notbe needed, and the covers may have racks applied directly to them at or near their ends, to engage with and be operated by a shaft with pinions, arranged as indicated at Z, or in other suitable manner.

In the construction of the cleaner for clean ing the cylinders or felts, I employ a suitable metal .pipe, Z, having a line or row of perforations on one side, and mounted in suitable supports, an, attached to the side walls of the vat. For convenience, the supports m are pivoted to the sides of the vat, or otherwise attached, in such manner that the pipe may be moved away from the felt or cylinder when not in use for cleaning it. To the pipeZ is connected a suitable swab, a, made of felt, cloth, or other suitable material, nailed or otherwise secured to a bar or rod, 1), and extending under the pipe or between it and the felt or cylinder to be cleaned, and adapted to rest in contact therewith when in use. This swab is,by preference,connected with the pipe by loops 1) p, which adapt it, if desired, to slide endwise thereon for effecting the more thorough cleaning of the felt or cylinder, and may be provided with a handle, as shown at p, to rock the pipe to cause the acid to flow from the pipe onto the swab; or it may be connected with a crank and suitable gearing, as shown at p, actuated in any suitable manner, for imparting an endwise movement to the swab.

The swab may be made by wrapping the clot-h or felt around the perforated pipe, as

shown' in Fig. 6, and adapting the latter, through suitable connection with its supplypipe, to be rotated in its bearings by means of a crank-handle, Z, or other suitable means. This latter construction is more suitable for the felt-cleaner; but the latter can be made in all respects the same as in the cylindercleaner.

The pipe Z may be connected with a supply pipe or reservoir, in any suitable manner, for receiving its acid for cleansing purposes, and may be rocked, as described, for feeding the acid to the swab, or the swab may be vibrated in contact with the cylinder or felt for cleansing the same while said parts are in operation, thereby obviating the necessity for stopping the operation of the machine, and saving time.

Aside from the features particularly described, the construction may be the same as in the patent referred to, or similar to other machines in common use.

Having now described my invention, I claim lower vat and containing two or more pulpmixing chambers, the overflow-gate a and the pulp-conducting pipe to, extending from said overflow-gate to said lower vat, substantially as described.
